SequenceIterator<IntegerValue> |
iterate()
Return an Iterator to iterate over the values of a sequence.
|

th - the type hierarchy cachepublic int getCardinality()
public IntegerValue itemAt(int n)
itemAt in interface AtomicSequenceitemAt in interface GroundedValuen - the index of the required item, with 0 representing the first item in the sequencepublic GroundedValue subsequence(int start, int length)
subsequence in interface GroundedValuestart - the index of the first item to be included in the result, counting from zero.
A negative value is taken as zero. If the value is beyond the end of the sequence, an empty
sequence is returnedlength - the number of items to be included in the result. Specify Integer.MAX_VALUE to
get the subsequence up to the end of the base sequence. If the value is negative, an empty sequence
is returned. If the value goes off the end of the sequence, the result returns items up to the end
of the sequencepublic int getLength()

getCanonicalLexicalRepresentation in interface AtomicSequencepublic Comparable getSchemaComparable()
In the case of data types that are partially ordered, the returned Comparable extends the standard
semantics of the compareTo() method by returning the value SequenceTool.INDETERMINATE_ORDERING when there
is no defined order relationship between two given values.
